This sourdough zucchini bread is deliciously spiced, moist, and packed with shredded zucchini. The perfect quick bread texture that uses sourdough discard or active starter.
Combine flour, cinnamon, baking soda, baking powder, and salt in a medium bowl and set aside.
In a stand mixer or large bowl, whisk melted butter and brown sugar until light and fluffy.
Shred two cups of zucchini, leaving the peel on. Add the shredded zucchini, vanilla extract, eggs, and sourdough starter to the butter and sugar mixture.
Fold the dry ingredients into the wet ingredients a little bit at a time until just incorporated. To keep the crumb tender after baking, it’s important not to over-mix the batter. Gently fold in any other add-ins you would like.
Preheat your oven to 350 degrees Fahrenheit. Pour the batter into a greased or parchment-lined 9x5 loaf pan.
Bake for 50-60 minutes. Test bread at 50 minutes with a toothpick or cake tester. Cool on a wire rack before slicing.
Long Fermented Version
Start 12-24 hours before you plan to bake the zucchini bread. Combine sourdough starter, melted butter, eggs, and flour, stirring well. Cover with a towel or plastic wrap and allow to ferment at room temperature for 6 hours.
Place the batter in the fridge and allow it to ferment for another 6-18 hours.
The next day, add brown sugar, shredded zucchini, vanilla extract, cinnamon, baking soda, baking powder, and salt to your fermented batter. Mix in any add-ins at this time. Mix on low to medium speed until combined. Don’t overmix.

No need to peel. The skin of the zucchini softens when it bakes, adding nutrition and a little color to the loaf.
Don’t overmix the batter. Stir just until combined to keep the crumb tender.
Let the bread cool for 10-15 minutes before slicing.
